Normally I'd just skim Robert Zubrin's Entering Space for quotes, but the copy's my brother's, and thus I left it behind when I moved to Toronto. Haven't been able to find a copy in the bookstores around here.

Mars has a lot fewer reasources, and thus cannot sustain a self-suficient base. I could do a more comprehensive response, but my reference material is on the far side of the country. Hence this topic.Samuel wrote:Shouldn't we be building moon bases first? The moon is alot easier to reach than Mars and easier to exploit for resources. Plus, if you skrew up you might get rescued.
I see I'm not going to get any pro Mars arguments here. Guess I'll blunder on alone as best I can.Junghalli wrote:A moon base before a Mars expedition actually makes good sense, because running a self-sufficient moon base will be good practice for trying to keep people alive on Mars, and the moon is a much easier target.
Sounds like you are killing your own argument here. Out of curiosity, what are your arguments for a base on Mars before a base on the Moon?The Romulan Republic wrote:Mars has a lot fewer reasources, and thus cannot sustain a self-suficient base.
Why would we bother? Mars is so far away, you could finish practicing on the Moon before colonists get there!Tsyroc wrote:I thought the argument for going for a self-sufficient Mars base was mostly because of water and more of an atmosphere being present than on the Moon. The main thing being the presence of water. The atmosphere comes more into play when thinking of permanent settlements, and I think people who really want to put self sustaining bases on Mars have pictures of a terraformed, or partially terraformed Mars that a significant amount of people would move to.
Personally, I'm of the play it safe notion of practicing on the Moon as best we can before sticking people so much further away.

Fucking typo. I meant the Moon has fewer resources.Darth Ruinus wrote:Sounds like you are killing your own argument here.

A century to raise the temperature. A thousand years for Earth-like atmosphere.Samuel wrote:Mars only advatage is it can be terraformed. Which takes over a century.
Again, you're really defeating your own argument here.The Romulan Republic wrote: A century to raise the temperature. A thousand years for Earth-like atmosphere.
Wouldn't that mean that any spacecraft taking off from Mars would have to pay about the same about of fuel/energy costs as one launching off from here? Wouldn't environments with less gravity be friendlier for lifting stuff off planet?Mars has closer to Earth gravity,
So... you want the colonists to be pelted by radiation and micrometeorites?minimal atmospheric protection from radiation and micrometeorites,
Ok.lots of frozen water (I believe more than the Moon)
Sure, good for research, but why can't we land, take some specimens and research them at the cheaper and closer moon base?and possibly life.
Sure, but it would be cheaper to do so if you are launching your stuff from the moon base first wouldn't it?And it can be terraformed.
I don't know much about that, so I can't comment.It would just take a while. Another big one is that it has a day/night cycle much closer to Earth's, so you could grow plants for food and air using natural light. That could save a fair bit of power, though I lack hard numbers.
He wants to avoid health problems from low gravity.Wouldn't that mean that any spacecraft taking off from Mars would have to pay about the same about of fuel/energy costs as one launching off from here? Wouldn't environments with less gravity be friendlier for lifting stuff off planet?
He is refering to the Moon. Mars has an atmoshere that, while thin, is thick enough so that shielding doesn't have to be as through as Mars.
So... you want the colonists to be pelted by radiation and micrometeorites?
I can admit the negatives, while still believing the positives outweigh them.Darth Ruinus wrote:Again, you're really defeating your own argument here.The Romulan Republic wrote: A century to raise the temperature. A thousand years for Earth-like atmosphere.
minimal atmospheric protection from radiation and micrometeorites,
Better some than none.So... you want the colonists to be pelted by radiation and micrometeorites?![]()

Thank you. Finally a useful reply.Ender wrote:Off the top of my head, the pro mars argument is:
1) Greater protection from radiation
2) Lower delta V from Mars to asteroid belt than from Moon to asteroid belt
3) Greater resources
4) Greater carrying capacity for population
5) Lower collision rate
6) Higher gravity (less biological adaptation)
7) Better science (lot more experiments to be done on Mars then on the Moon)
Easier to import material (meaning redirect asteroid and comets; lower delta V to move things the further our of system you go due to decrease in Sol's influence)
9) Greater access to energy resources (geothermal and fusion)
And a quick google search turned up this Zubrin's original speech that he expanded on and turned into his books.
These are only Mars vs Moon arguments, mind. Like D said, best course of action is space habitats. I just went with this because it is the topic at hand.The Romulan Republic wrote:Thank you. Finally a useful reply.Ender wrote:Off the top of my head, the pro mars argument is:
